We had a new bishop set apart yesterday and all of the information was put into MLS. The Counselors appear on LDS.ORG but the bishop does not. LDS.ORG still lists the old bishop. How do I fix this?????

You didn't mention what your calling is. Counselors in a bishopric need to be entered in ward MLS, which it sounds like you have done. But the bishop needs to be entered in stake MLS (typically by the stake clerk) using a Leader and Unit Change Request. That change will then be processed manually by someone at Church headquarters. If that gets transmitted from stake MLS on a Sunday, in my experience it will get processed by Wednesday or so, and then the bishop will show up on CDOL and thus in LDS.org.

As has already been mentioned the bishop position is a tier one position and must be changed using a LUCR in stake MLS. MLS allows the bishop to be changed in local MLS. However, this change is not sent to the administration office and does not update or affect any other records or systems outside the local MLS.
